Rated 4 out of 5 by mscrysta new, easier way to give monthly meds
I bought this product instead of Triflexis as it does the same thing but costs about half the price! We are only one dose in and dealing with a major flea infestation right now so cannot say YET how truly effective it is. Fingers crossed because the price and double-duty of this pill make it a winner...

I have used this product for years and I live in the south with a lot of fleas. I have not had one flea problem in the house. I like this product over all the others on the market. My dogs health has been and still is perfect. I will continue to use and recommend others to use this product.

This is the only heartworm protection that both of my dogs can take without it coming back up. I love the fact it covers more than just heartworms. I have given this to all my 4 legged babies. Best buy for the money I highly recommend this product!!!!! :)

So excited this product is available again. All others made our boys sick and were too big to swallow (as they did not want to chew them).

Rated 5 out of 5 My picky pup loves it!
I have one dog that will eat anything, and the other who will eat around pills - no matter what I put them in! Sentinel is like a treat to him!! He eats it right up! They never got sick from it. They don't have any problems with fleas or anything like that. Definitely recommend!

We switched to Sentinal a few years ago after getting skin reaction to the topical preparations. With three Goldens, A Mom and two litter mates, we have had no problems except the price is exorbitant, twice that of a similar crewable, Hartguard.

Rated 5 out of 5 Flea-free Shelties!
I highly recommend this product. I give it to my two Shelties, ages three and two and a half, and neither one of them has ever had a single flea. I live in Florida where fleas are a year round problem.

Rated 5 out of 5 I highly recommend this product. I have two Shelties, one is almost three years old, and the other is two and a half years old. Have never had a flea on either one of them, and I live in Florida, where fleas are a problem year round.

Rated 5 out of 5 I trust this product
I am very pleased with Sentinel and completely trust this product. I used Comfortis for approximately 5 months and both of my dogs had seizures once a month for the 5 months that I gave them the medication. It was awful. After repeated trips to the vet and numerous tests we finally figured out the Comfortis was causing the seizures. I wasn't aware seizures are a possible side affect from that medication. I also tried Frontline and it seemed to really irritate my min pins skin when I applied it so I immediately stopped that. I haven't seen any side affects in either dog from the Sentinel and I have been using it for the past year. I have not seen fleas on either dog either. I'm not sure if certain medications affect certain breeds however I found it odd that both of my dogs suffered seizures approximately one week after the administration of each dose of Comfortis.

Love love love Sentinel! Have used it on my Rat Terrier for almost 2 years now and have never had any issues. The convenience of one product for both heartworms and fleas is fantastic!

Rated 5 out of 5 No side effects
I had always used the liquid flea treatment for years on my dogs. The last two dogs I had, toy poodles BOTH developed cancerous tumors. The male used to scratch at the spot where I would put the liquid and it would get red and irritated for a few hours. He was 11 years old and she was almost 15.
She tolerated the medicine better, but it still got her in the end. I totally believe its what gave them both cancer. One of the liver the other one his stomach cavity. I have 2 new dogs. They have been on Sentinal for 2 years as of Aug. I have had no problem and I like the fact that it protects for all the parasites and the fleas so I only have to give one pill to each of them once a month. I have not seen one flea on either dog. I highly recommend this product.

Rated 2 out of 5 Extreme Side Effects
I can not recommend this product. I gave it to my Choclate Lab at my vets recommendation. The first tab she took she became lethargic , could not eat within the day. She could not get up. Very hard to find ANY information as to the testing done. Got a refund. I went back to Heartguard and Frontline. I have used them for many years on several breeds with no issue.

Rated 5 out of 5 Long-term solution, not a quick fix
True, Miss South Carolina, this product does not kill fleas. Fleas live just a short time (a week or so) and reproduce prolifically. This product prevents a flea colony from gaining or maintaining foothold in your home. We have three Jack Russells in a flea-infested, pet-friendly island community and have seen zero fleas on them in the past four years. The flea population where we live has apparently developed an immunity to Frontline as it has little or no effect here. Sentinel took about six weeks to begin showing effect but since then, it has been the complete and total cure we had hoped for. Best thing we have ever used, but it took some patience.

Rated 5 out of 5 15 year user of setinel
Used for 2 dogs large and small breed and had excellent results. I had next door neighbor who had regular flea infestations and my dogs never had an issue...not even visual fleas...even tho my vet does not carry it, in fact it's hard to find a vet who will carry it (contracts with competitors) but I rave about it and despite some vet critics, I highly recommend it

Rated 5 out of 5 prescription
Do I need a prescription when ordering Sentinal for my dog? I know the strength she needs as I have bought it from the vet before.

Rated 5 out of 5 Charlie & Harry
Charlie was our first pet in Florida, a Llahsa Apsa. He lived to be 18yrs. we gave him Sentinel tablets for at least 10 years. It was the best.
Today we have a rescue dog, lab & beagle mix. His name is Harry & does not like the topical products so we put him on Sentinel, he thinks they are treats. No mess and no fuss.

We have given Sentinel to our pets for the past 25 years. We have never had to worry about our girls using this product. We have had the pleasure of living with six loving girls in the past and now with two new toy poodles. This is a wonderful product!!!!!

Rated 5 out of 5 Easy and works!
I love this. My dogs will eat it no problem and so much easier than messing around with topical solutions. On large dogs the topical meds are hard to apply, you have to spread it over the whole body and it is hard to judge how much to apply to each area, I always have some left over because I am afraid I won't have enough at the end. Also it is difficult to part the hair on very short haired dogs. I made sure the dogs were flea free with Advantage and then started this pill, haven't seen a flea since..it won't kill adult fleas so it is best to get them off first. LOVE PetcareRX paw points and coupons...saving a lot of money, PLUS their prices are the lowest to begin with !!!!

Rated 2 out of 5 Does Not Kill Fleas
Purchasers should be aware that this product will NOT kill the fleas you see on your dog. It sterilizes the fleas and prevents them from reproducing. If you are looking for something that will kill the fleas you see on your dog, you should get Frontline Plus for Dogs. After my vet explained this to me, and online reasearch easily backs it up, I quit using this product since it won't do what I need.

Rated 3 out of 5 Worked up until now
I have three dogs and have been using this product for over a year. I just found fleas on one - she has white hair so it was easy to see them crawling around. I am considering switching back to Heartgaurd and just using a topical flea medication now.

Rated 5 out of 5 No More Fleas!
My dogs are on Sentinel now and Program the year before. Prior to discovering this medication, I tried every available spray, powder and spot treatment without luck. The fleas in South Tampa, Florida can reproduce amazingly fast and nothing worked - until I used Program. Because of it, I switched to Sentinel for the heartworm protection instead of using separate drugs. Both of my dogs love the flavortabs and consider them "treats". It's always good when the dog likes it, right?

Rated 5 out of 5 Great Product!
I've used this product for 2 years now and I love that I do not have to worry about fleas and paracites on my dog. I have never had any issues with my dog bringing any "buddies" from the outside!
